Language Blog

Part 1:
First off I thought it would be somewhat easy to not speak for only 15 minutes, but it was frustrating!  My mom was talking to me and I would just nod or shake my head and she started questioning if I was ok.  I would just shrug my shoulders and keep nodding.  It sort of put my mom and I in an awkward situation and conversation.  My mom did alter her way of communicating with my absence of communication.  She quickly changed the subject of how our days were going, to if my boyfriend and I were ok.  She started going on and on about boys and if it make me feel better if I wanted to go shoe shopping with her that day.  I think the 15 minutes were up and I took her on for the shoe shopping:)
I personally think if two entirely different cultures met up, I believe it would be better to use hand signals and such rather than talking.  Even though it was hard for me with my mom, yet my mom is used to me talking a lot.  So for me not to talk much and just use hand motions it was bothersome for her.  I work at a restaurant and a lot of the cooks speak Spanish.  Most of the time when I started out I would use hands signals and they would too.  We understood completely rather than trying to speak the other language to each other.  Now I caught onto Spanish and can speak it pretty decent. 
If one culture could speak and did not use hand gestures and another culture did not use symbolic communication but did use hand gestures, then I think the culture that could speak would have a better understanding of learning the hand gesture language.  This is because hand gestures you can point out certain things.  The hand gesture culture would have trouble speaking because they wouldn’t know what certain things were verbally.  So personally I think it would be better to know hand signals but in the long run the culture that was able to speak would be better off.

Part 2:
            I am the type of person who uses hand gestures a lot and a lot of expressions when I talk.  I am also a very smiley person so this part of the assignment was even harder then the first part!  I ended up doing this part with my boyfriend and I used my hands on accident and then I started laughing and my boyfriend thought I was crazy and I ended up only accomplishing like 4 minutes of this part!
I really had a fun time doing this assignment, plus I got a free pair of shoes out of it yay!
I definitely think that people who have adapted to reading body language can almost in a way speak two languages; body language and actually speaking.  I think even military and others use sign language when they are in a quite environment.  I actually can not think of an environment not to read body language except maybe in a classroom and you are taking a test.

Piltdown Man

The Piltdown man was a remarkable discovery recognized in the old-fashioned village of Piltdown, England in the early 1900’s.  Scientists were awestruck by the peculiar missing link between humans and apes that arose and was founded by Charles Dawson, an amateur archaeologist.  Charles Dawson publicized some magnificent discoveries in regards to developing “academic credibility”.  In 1912 Dawson spread his findings of coming across a peculiar human skull that would compete with the German’s “ape man”.  This brought the attention of Sir Arthur Smith Woodward, a noted geologist, who later accompanied Dawson and a group of laborers to an endless summer of digging.  On December 18th, 1912 the public awaited eagerly for the “first glimpse of mankind’s earliest ancestor”!  Dawson was pleased to announce to the public about his findings and that “of all the places in the world where mankind could be born, he had chosen England”.  For 40 years this striking discovery helped scientists and sky rocketed to being the “reigned supreme”.  In 1953, the news broke out, “Piltdown Man was a fake”!  Scientists had been fooled, the British embarrassed, and the scientific world was in chaos.
            Many human faults came into play in this scenario.  For 40 years, scientists had been tricked and deceived by this “fake missing link”.  It took a scientist named Kenneth Oakley to perform a chemical test to date the fossils.  The results were preposterous and to the scientists’ dismay the fossils were a fraud.  The Piltdown man had filed down teeth, a stained skull, and was actually just an old ape’s jaw.  How could anyone forge and plant this mastermind hoax?  Pointed fingers were quick to locate Charles Dawson for this horrible act because he was the one who found all the fossils.  Charles Dawson wanted publicity; he wanted Britain to be known as the home place to the missing link.  Other countries like Germany, France, and Spain had already made some remarkable fossil discoveries, while Britain had none.  Although, Dawson could have been at fault, another scientist took the stage.  Sir Arthur Conan Doyle, the creator of Sherlock Holmes and a theatrical kind of character, was keen on hunting for fossils.  Many scientists tried to make a fool out of Doyle, so it seems to be only fair if Doyle made a fool out of them.  Doyle had been living 7 miles away from Piltdown and was quick to pick up Dawson in his motored car whenever Dawson needed a ride.  Could Doyle have been the mastermind behind this famous act?  Whoever it was, this stunt that was performed, negatively affected the scientific process.  Nobody could trust science anymore.  What was real?  What was fake?  Did scientists lie about everything to the public?  It definitely impacted the scientific world in the wrong way.
             Whoever took act in this forgery, they took skill and knew what paleontological and anatomical tests the specimen would be given.  Scientists used a fluorine test in order to test the age of the fossils.  When they performed these tests the results came back that the bones were only about 100 years old.  The teeth in the jawbone had been filed down and one tooth, had been rushed to be made, that you could tell it had been painted.  Scientist finally put out the correct results, that in fact these bones actually belonged to a female orangutan and were not apart of the missing link.
I do not think it would be possible to remove the “human” factor from science.  Perhaps it would remove some errors, but one always learns from the wrongful acts that they perform in the past.  Humans always strive and compete to be the best.  Competition is exceptional when it comes to science.  Aiming to finding the “missing link”, cure for cancer, or just the best peanut butter jelly sandwich; humans must always be a factor.  I believe history helps reduce having errors like this happen again.  Humans are quick to learn and we build our knowledge off of mistakes in the past.  I believe this is a good example of science correcting itself.
Life Lesson of the Day:  Humans by nature have an inherent desire to soar above the rest, even if it means to cheat.  “Tis my opinion every man cheats in his own way, and he is only honest who is not discovered”-English Playwright.

Body Size and Sexual Dimorphism

Lemurs live in the trees and bushes of Madagascar and the Comores Islands, in which they have a strict diet plan of leaves, fruits, and insects.  Lemurs have reasonably good grip for hanging in trees and rarely come to the ground, except the Ringtail lemur, that actually spends most of its time on the ground.  When lemurs are born, the mother carries her baby in her mouth until they are old enough to hang onto their mother’s fur.  Female lemurs and male lemurs are rather difficult to differentiate from each other.  Lemurs lack sexual dimorphism in size, yet true lemurs show sexual differences in their fur coloration.  Black lemurs have a strikingly obvious difference sexual dimorphism in fur coloration.  The Black lemur got its’ name from the males’ fur coloration, which is black.  However the female Black lemur is brown in color.  Lemurs vary greatly in size and include the smallest primates in the world and the largest ranging in size from the Madame Berthe’s Mouse Lemur (1.1 oz) to the recently extinct Archaeoindris Fontoynonti (440 lb).   Lemurs lack any common characteristics that make them stand out from other primates because they evolved unique combinations of abnormal traits to cope with Madagascar’s harsh climate.

Spider Monkeys
Spider Monkeys, like lemurs, live in trees and rarely come down to the ground.  They reside in the evergreen rainforests and live mostly in the upper canopy.  In order to swing from branch to branch spider monkeys have evolved to possess a third hand!  Their tail is very muscular and actually has a patch of skin with distinct patterns of lines like a fingerprint.  Their tail is able to support their entire weight while their hands forage for food.  The spider monkey is not characterized by a high degree of sexual dimorphism.  However the females play a more active leading role than the males.  When an intruder approaches a Spider Monkeys’ nest, the females will act uncontrollably, displaying wild behaviors and rough barking.

Baboons, like humans, are capable of living in a wide range of habitats.  They are different from lemurs and spider monkeys when it comes to living because they are ground dwelling primates.  Baboons are very clever and like to interact with people.  They are treated as vermin rather than wildlife because they can be agricultural pests with their crafty intelligence.  Baboons have a striking size difference between sexes and coloration.  The males are usually silver/white with a bushy mane around their head and their faces range in color from tan to red.  The females are usually just brown.  Males are drastically bigger than the females in size and are usually very aggressive and protective of their females.

The Gibbons live in different parts of southeast Asia, from Burma, North Sumatra, and China to the Malay peninsula.  They dwell in branches and actually do not make nests.  Instead, they huddle with other gibbons or sleep alone.  Every morning, upon awakening, the gibbon uses a territorial hooting call, which is usually started by an adult female and last about a 1/2 hour.  The Gibbon does not show sexual dimorphism in size but it does show it in color.  Males usually have a coarse black fur and black skin with white fur on their cheeks, while the females are a golden or reddish color with black faces.  They are very distinguishable between each other.

Chimpanzees usually live in rain forests and wet savannas.  They spend most of their feeding and sleeping time in trees, yet they spend equal time on both land and trees.  The chimpanzee is very intelligent and social and is the mammal that is most like a human.  They have no tail surprisingly and they have short legs with long arms.  Most of their body is covered in hair, except their ears, face, fingers, and toes.  The females and male coloration are very similar, but they do differentiate in size greatly!  The females are usually 2-3 ft tall while the males range about 3-4 ft.

The environment seems to have a great deal of expression on the physical and behavioral traits of these 5 primates.  Gibbons, lemurs, and spider monkeys are very moveable and quick in their trees and canopies they live in.  Chimpanzees and Baboons are very quick witted and intelligent, living on the ground near humans and being exposed to villages.

  Homologus Traits
  a.  Scorpions + Spiders = Shared Homologus Traits

b.     Scorpions and spiders are both are very similar and different from each other.  Spiders catch their prey in either webs or by hunting on the ground for insects and beetles throughout the day.   Scorpions on the other hand are unable to see very well, so they reside during the day in cool places under rocks or in burrows and only at night are they able to hunt for food; digesting their food in liquid form.  Both spiders and scorpions develop three stages of growth throughout their life.  Spiders begin as an egg, then the nymph, and last an adult.  Scorpions experience molting stages throughout their lifetime.  Even though these two species have different lifestyles and look completely different they both share common traits.  Both spiders and scorpions share resemblance in their abdomen and the cephalothorax.  They also both have 8 legs, which is sought out to be one of scariest traits to possess!
c.     Both the spider and scorpion share a common ancestor.  They both are classified as arachnids.  They are not considered insects because they do not have antennae or wings.  They possess an exoskeleton and an internal structure of cartilage, which certain muscle groups are attached!

Analogous Traits

      a.  Platypus vs. Duck  
b.     The platypus and duck both share some similarities.  Both the duck and platypus have bills, in which they both use to dabble through mud to find food.  They also both nest and lay eggs!  Which is surprising because the platypus is not related to the duck at all.  The platypus is considered a mammal, yet mammals are usually considered to give live births.  The reason why the platypus lays eggs is because it does not have a placenta.  A duck however is not a mammal, and is instead    classified as part of the bird group.
      c.  Birds descended from dinosaurs, which is interesting because I was reading an article and they found a dinosaur in China with feathers!  My dad is a geologist and actually has a friend who is a paleontologist and they are studying chickens’ and ducks’ behaviors and personalities to get a better insight into dinosaurs’ personalities.  Scientist have also discovered that the “scary” T-Rex that Hollywood portrayed as being such a frightful monster is actually a scavenger and couldn’t even run fast.  Besides all this dinosaur talk, platypus is considered a mammal, which is entirely different then a bird.  So, that is why the platypus and ducks have analogous traits
